Labels: Needs-Bisect
The regression range only has three blink changes none of which touch rendering. Requesting a re-run.
Labels: -Needs-Bisect
Re-did the task as per Comment# 2.
Removing Needs Bisect label as of now, will update the issue once the re-run is successful.
Thank You.

Doing a manual bisect.

Comment 6 by e...@chromium.org, Mar 31 2017

Even the known good from the latest bisect run fails for me. Expanding the range for the manual bisect run.
